There is this misconception that using an air filter in the shop is going to help with dust collection and protect your lungs. The bottom line is to capture the dust AND particulates as close to the source as possible. Anything in the sub-5 micron level could take hours to settle and “stirring up” the air with a cleaner doesn’t let those particles settle, rather will keep them in the air. Unless you are planning on keeping your head near the output of the air filter, you will not see the benefit. I made a filter with all the top of line filters and my old 4-speed furnace fan. It seemed to work for a short time but when the filters start to get full, air flow is significantly decreased. I am considering taking it out and filling the space with drawers which will keep the dust off my better tools better than any air cleaner.

Like I said before, use the mask for now and save for a cyclone when you move…

I don’t believe in using a DC and air filter and wouldn’t spend a dime on one. I think eventually, you will find the dam thing.
